Step 6 · Reassemble and Test the Drain

Once you believe the clog is cleared, carefully reassemble the P-trap, making sure the slip nuts are properly threaded and the plastic washers are seated correctly. Hand-tighten the nuts firmly. Place your dry towels back under the reassembled trap. Turn on the hot water tap and let it run for several minutes. Watch all the connections you touched for any signs of dripping. If you see a leak, you may need to tighten the slip nut a little more (no more than a quarter-turn with pliers). Once you've confirmed the drain is flowing freely and there are no leaks, you can clean up your tools and put everything back under the sink.
